Value Types and Reference Types
A data type is a value type if it holds the data within its own memory allocation. A reference type contains a pointer to another memory location that holds the data.
Value types include:
* All numeric data types
* Boolean, Char, and Date
* All structures, even if their members are reference types
* 1Enumerations, since their underlying type is always Byte, Short, Integer, or Long
Reference types include:
* String
* All arrays, even if their elements are value types
* Class types, such as Form
* Delegates
You can assign either a reference type or a value type to a variable of the Object data type. An Object variable always holds a pointer to the data, never the data itself. However, if you assign a value type to an Object variable, it behaves as if it holds its own data.
